I hear you. I don't think people are willing to pay $1000 to $1500 for these things. As far as quality goes, if I am doing it, it's not going to be cheap junk, not worth making in my book. Even if I could drop my build time to 10 hours, material cost to $500, and sell for $1000, I am not sure its worth my time. If I sold for $1500 sure worth it at that point.
I disagree.
Your market would not be everyone. If you can make them nice enough, nice wood, good shelving. Auto lights. Good locks... i bet you could sell for 2000-3500 quite easily. I know most people especially on here will say that is to much, over $350, but its not. Your customer would be the 1%. But it would have to be nice.
